To all whom, it may conce/m.'

which double Webs serve u. further function Be it known that I,Fnunnnicu BENNETT, nvenswood, county of Queens, Stute ol New. York, haveinvented Acertain new ond useful Improvements in` Cushions, of which thefollowing is :t full, clear, and exact specification, such as willenable others skilled 1n the art to which it. appertains to make :1ndusethe sil-nie.

My invention rel :ttes to a cushion intended particularly for seats incars and other pubof cushions. in which a. frame carries =a.'nl1mbeI-.cf springs over' whichj flexible steel or iron sheetsy are arrangedfurnishing izilexiblesupport for the covering of woven; rotan or.such-other material ns maybe e "ployed to c o'ver..v the cushions. i l i.z f

To ncconiplish this, thefiunges 10 and V13 of the freine strip at the points Where the bends areto be 4foiined'nre cutor slit "us indicated :it lnnd 16 in Fig. 11,leaving the n'ebs 11 und 14 intact.

' i Extending against. the 'frame und .on the bottom .liunge 12 supports19. These resting the cushion generally couo1-'rectangular und is madeup in u peculiar manner of n sheet metal strip. This strip is folded orbent longitudinully to producen top fia-nge l0, :i vertical main web 11,a bottom liange 12 and a. secondsry vertical web 14. These parts are allformed of au integralsheet of metal by making the requisite foldstherein. The webs-11 und ltlie against euch other and the Iinngc" 1i'has a double thickness produced by bending the metal upon itself asshown in the drawings, and particularly in F ig. 4,' This produces anextremely rigid structural for'm, having the' strength of channelor'U-iron` 'llle Atranne of spring supports are constructed of metalsheets with their edges turned up to vforni flanges Q0 which strengthenthe supports; and the ends o`f the supports :1re lirxulv riveted to thefianges 12 :is indicated at Suid spring supports have tongues Qinstruckup from them and these are adapted to be bent over the bottomconvolution of the spiral springs 21. here shown there ai'ejthree springvsupports 19 and three springs for each support. Said springstaperupward 'and ere seated on the supports between the tiange's 20. -Bymesns ofthe tongues 23, the 4springsfare readily seund n mliing rigidconnection :it this point.

thereof are spring 1 ion strips 27 are thus supported by springs ened'asthe drawings show, the upperedge double webs, I not onlyfgreatlyincreasethe and cheapness than any cushion heretofore tical; and thelower Harige having a double g thickness formed -by ben spring supports19 and the` ends of the cushion-strips are bent downward as indisarethen riveted by fastenings webs. To prevent the upper edge of the weblongitudinally to cured and by a method which is cheap and effective.

At their upper ends the springs engage buttons 25 and these are fastenedb rivets 26 to the licxible cushion strips 27. f these strips there isone for each row of vsprings 24' and'f'said vstrips are preferablytransversely corrugated to give them flexibility, and also tofurnishbearings for the raten orvother covering of the `cushion. Theresilient cushand the combined elasticity of such parts amply producethe necessary yield or give tothe cushion. The cushion strips 27 eX#tend across the top of the frame 'from one side to the other .thereofVparallel with the cated at 28 and introduced between the u per edges ofthe webs 11 and 14. These en s 28 which pass \through said vends andthrough both of the 11i-from projectin toutward, .owing to the insertionof the en s of the strips 27 and thus preventing a ,sharp edge, saidweb'is shortlying below the upper extremity ofthe web 11. It willtherefore be seen that Aby providing the frame of the cushion with theKnown. l

Havingthus described my invention what I claim as new and desire tosecure by Letters Patent of Ithe United States, is:

1. A cushion, the frame whereofis oonstructed Aof a single piece ofsheet metal bent lproduce a channel or U- iron cross-sectlona ing themeta-l upon form, the web being verlongitudinally to producev a channelor U- iron crossfsectional form, vthe web being vertical and the lowerfla-nge having a double thickness formed by bending the met-al uponitself, and such metal extending from the base of the lower flangeupward along the said web to form a secondary 'or auxiliary web,springs, means forA supporting them o n the frame and avc'ishion elementextending over the springs, said cushion element' consisting in a strip,theends .of which are extended into the. space between the first--na-med and secondary webs of the frame and fastened thereto.V Y

3. A cushion, coin rising a frame having vertical walls and)V angesconstructed of a singlepiece of sheet metal, the lower Hanges andvertical walls being reinforced by'bending the'metal back and upwardupon itself, spring-supports seated upon vthelower Hannes, lspringssecuredupon the supports, and a cushion element-,supported upon saidsprings and secured. between the double vertical walls of theframef 4. Acushion-having a frameformed'of sheet metal folded longitudinally toproduce a channel with a vertical web and horizontal extending flanges,the metal forming one of said flanges being bent back upon itself toform said .liange of double thickness and both of said flanges being cuttransversely at a plurality of points at which point-s the web is bent'to form the corners of the frame, causing the adjacent portions of thefianges to loverlap one-another, and means for securing` together saidoverlapped portions.

In testlmony 4whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
